Abstract

PURPOSE:To maintain safe sanitary circumstance and to prevent a disease due to long-time work by starting measurement simultaneously with the operation start of an operator and generating a time elapse signal from a timer after a prescribed time to press the operator to rest and giving the operator a rest surely at intervals of a certain time. CONSTITUTION:When a power switch is turned on to start a system, a timer 3 starts the operation, and a time-up signal is outputted when a prescribed time elapses. A picture/voice control part 2 receives this signal to display a message on a picture display device 1 and operates a speaker 5 to press the operator to rest. When a confirmation key is inputted, the message is erased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an image quality display device, and is particularly used in office automation equipment and the like.

[Technical background of the invention and its problems]

With the spread of office automation equipment such as personal computers and word processors, and the diversification of work that uses computers, the number of specialized workers has increased! Increasingly, office workers are also faced with image display devices to operate them. Staring at the display screen of an image display device for a long time causes fatigue and is likely to cause visual impairment. There is a trend to establish various regulations regarding the environmental conditions and work contents of work using image display devices, but the most effective method is to set rest periods intermittently during work. This is widely known.

However, providing such a rest time is only done at the discretion of the operator or administrator, and no response is taken on the image display device side.

[Purpose of the invention]

The present invention was made to solve such problems, and an object of the present invention is to provide an image display device that can maintain a safe and healthy environment during work and prevent diseases caused by long hours of work. shall be.

[IR requirements for invention]

In order to achieve the second object, the present invention includes an image display device, a timer that outputs a time elapsed signal after the time required for rest according to the operation time of the operator, and a timer that outputs a rest message based on the time elapsed signal. and a control section that outputs the output. Therefore, it is possible to reliably give the operator a break at regular intervals to prevent fatigue.

[Embodiments of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an image display device according to the present invention will be described in detail below with reference to the drawings.

FIG. 3 is a perspective view showing the appearance of an image display device to which the present invention is applied, and shows an example of use in a parts-pull computer.

This personal computer is typically divided into three parts: a main body 14, a keyboard 17, and a CR display device 11. A message display area 13 is secured in a part of the display screen 12 of the CRT display device 11, and a message urging the user to take a rest is displayed here as will be described later. Moreover, the speaker 15 can also be provided on the side surface of the main body part 14.

FIG. 1 is a block diagram showing an example of the configuration of an image display device according to the present invention.

According to the figure, an image display device 1 such as a CRT has a screen/audio side m.
This screen/audio control section has a timer 3.
, a data input section 4 such as a keyboard, and a speaker 5 are also connected. This timer is for giving a trigger to the screen/audio υ1111 section to output a rest message after a predetermined time.

Next, the operation of the present invention will be explained with reference to the time chart 11 in FIG.

Time t. The system is started by turning on the power switch 16 in FIG. 3. When the power is turned on, the timer starts operating, and a time-up signal TIM is output at time t1 when a set time (for example, one hour) has elapsed. The screen/audio control unit 2 that receives this time-up signal IM forces the message on the image display 1 that has been determined in advance and is stored in the memory vtia in the control unit 2 into the message display area 13 of the screen 12. Output. This message is, for example, one that urges the operator to temporarily take his eyes off the screen and rest his hands in order to recover from fatigue because a certain period of time has passed since the start of the operation.

This message is erased from the screen 12 by the operator's confirmation key or by software processing after a predetermined period of time has elapsed.

Next, at time t2 when time T has passed again from time t1, the timer outputs a time-up signal TIM, and a message is output. Similarly, a message will be output each time time T elapses.

Note that the content of the message may be changed depending on the elapsed time. For example, if you want to send a message urging people to take a long rest every 3 to 4 hours, prepare multiple timer systems, and use a timer that outputs a time-up signal every hour to output a message requesting a short break. It is sufficient to use a timer that outputs a time-up signal every time a stop request message is output.

In addition to outputting a message on the screen, a warning signal can also be output from the speaker or block 1F at the same time as the message is output on the screen, or a voice message can be output from the speaker 15 using a voice synthesis IC. You can also.

In the embodiments described above, the present invention is applied to an image display of a part-pull computer, but the present invention is not limited thereto, and can be applied to devices with an image display such as word processors and online terminals. Furthermore, the image display device is not limited to the CRT as in the embodiment, but can be applied to any display device that is viewed by an operator, such as a liquid crystal display device (LyCD) or a plasma display device (FDP).

Furthermore, in order to measure time more accurately, the timer can be configured to start counting when any key is operated after the device is powered on.

Furthermore, versatility can be improved by making it easy to set time and messages as needed.

〔Effect of the invention〕

As described above, according to the present invention, the timer is driven when the operator starts an operation, and a message urging the operator to take a rest is output based on the elapsed output of the timer for a predetermined period of time, thereby ensuring a reliable rest. This prevents worker fatigue caused by staring at the screen for long periods of time.
